Display panel having touch detection function and control method for the same

A display panel having a touch detection function, comprising:

• a display element;
• and
• a touch element, including:
• a touch scanning chip;
• a scanning selector connected with the touch scanning chip, and disposed outside the touch scanning chip;
• and
• multiple touch electrodes connected with the scanning selector;
• wherein, the touch scanning chip outputs a selection signal including a control signal and a scanning signal to the scanning selector in order to selectively connect the multiple touch electrodes to the touch scanning chip such that the touch scanning chip sequentially performs a touch scanning operation;
• the number of ports of the scanning selector used for connecting the touch electrodes is greater the number of ports used for connecting the touch electrodes to the touch scanning chip;
• wherein, the scanning selector includes multiple switching elements;
• the control signal of the selection signal outputted by the touch scanning chip directly controls the switching elements of the scanning selector to be selectively turned on or turned off in order to selectively connect the multiple touch electrodes to the touch scanning chip in order to input the scanning signal of the selection signal into the multiple touch electrodes;
• the display element includes multiple gate lines disposed in parallel and a gate driver;
• in a display time of one frame, the gate driver sequentially performs a gate scanning operation to the gate lines, wherein, a time interval is disposed between two adjacent gate scanning operations, and the touch scanning chip performs the touch scanning operation in the time interval.
